Supply flexibility and power-down budgeting
Operating from 1.8 V to 3.3 V, the DSC1001BI2-031.2500T spans the common logic supply rails without an external regulator — a single voltage rail on a 1.8 V microcontroller or a legacy 3.3 V bus drives the oscillator directly. Maximum active current is 7.2 mA. This matters for battery-backed modules where the clock source is the largest quiescent load in the system.
The DSC1001 series is an in-production Microchip portfolio; the DSC1001BI2-031.2500T is quoted to order against BOM quantities through independent distribution.
4-SMD no-lead package, 5.00 mm x 3.20 mm body with 0.90 mm seated height. No via-in-pad or microvia required; a two-layer board handles the fan-out.
